Abstract:
The rate of erectile dysfunction after radical retropubic prostatectomy is from 10% to 100%. The prevalence of erectile dysfunction after nerve-sparing radical prostatectomy is more than one third. In the patients who had undergone bilateral NS, 72% responded to sildenafil, 71.7% and 59.7% responded to 20 mg and 10 mg of vardenafil respectively. For all randomized patients who received tadalafil, the mean percentage of successful penetration attempts was 54% and the mean percentage of successful intercourse attempts was 41%. For the subgroup with evidence of postoperative tumescence these values were 69% and 52%, respectively. No head-to-head trials have been performed with sildenafil, vardenafil and tadalafil in treatment of erectile dysfunction after radical prostatectomy.

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
